Appoligize if my reply navigation is wrong but spied Harold's good advice to tap the gallery holes...definitiely more reliable path...is that way brass plugs appear to not be readily available?
Thanks - Joe Mulqueen

When I had my BJ8 engine overhauled the shop who did the work--a
well-known local outfit--could not find properly-sized freeze/casting
plugs, so he bought oversized metric ones and machined them to fit. He
didn't mention the gallery plugs but, presumably, a shop could do the
same for them.

They dissolve when the block is hot tanked. It is a common item; I am surprised the machine shop does not have them and did not reinstall them after cleaning the block.
They are core plugs, items 2 and 3 on the Moss website.

Perry,
Tap all of the holes for a standard NPT plug. Use plugs that tighten flush with a hex key. All of those plugs should have been removed for a more thorough cleaning.
Regards,
Harold

I would suggest that you contact Core Plugs International. They seem to have everything.
I buy brass ones for all my engines from them.

Perry, when we did my BT7 motor I seem to recall initially having trouble sourcing the correct size plugs. Then I found this company - Core Plugs International - the name says is all. All they do are plugs and they were great to deal with.

And don?t forget to seal the internal oil channels in the block, I?m thinking of the channel from left to right and the one that goes up to the cylinder head. When you clean the block all the puriosite in the cast iron is exposed for the oil pressure, which is higher than the coolant pressure, and you will eventually end up with the deaded oil in water mess.
There has been kits in the market to do this from the usual suspects. Magnus Karlsson helped me with my block some 15 years ago. We screwed in threaded pipes in the oil ways.
